Risk Assessment of Batch Sulfonation Process using Fault Tree and Bowtie
Abstract: The current study looks into the batch reactor's sulfonation reaction's safety features. Acetanilide, thionyl chloride, and chlorosulphonic acid are used in the sulfonation reaction under consideration to generate acetyl sulphonyl chloride as well as by-products such HCl and SOx. Steam starts the process, which is exothermic in nature. Water is then chilled to maintain a temperature of 50°C and a pressure of one atmosphere. The Hazard and Operability (HAZOP) analysis …

The Importance of Safety Engineering in the Design and Assessment of Foundations
Abstract: In safety engineering, ensuring the stability of structures under lateral loads is a critical aspect of foundation design. Lateral forces, such as wind, seismic activity, or other environmental pressures, exert overturning moments on columns, which must be carefully managed to prevent structural failure. To maintain stability, the overturning moment at the foundation base, generated by these lateral loads, must always be less than the restoring moment produced by the soil's …
